I've had better success with aftermarket than OE about 75% of time. Hence why I said it's more opinion based. Just like my Anker 3100 is better than the Samsung battery 3100 that came with the note 2.
99% of reviews anywhere are based upon the customers experience/opinions. Apple chargers always sucked for me. HTC chargers had many issues in the past.

I am not talking about reviews. I am making my suggestion based on science and comparisons to other chargers and knockoffs from china. If you're buying a flagship phone, buy a flagship charger. And a good USB cable. Cables make a hell of a difference in electronics that can accept more than 500mah charging.

I am talking about all chargers in general. OEM chargers are better than the belkins, tankers and whatever. I read a couple very good articles about how good or bad chargers are. The ones that come with our electronics are usually the best. USB cables vary, sometimes even within the same models. The Samsung and apple chargers are really the best value when you consider longevity, heat, reliability and some other factors I am not qualified to explain.

Yes perfectly safe.
Amps (current) are drawn/pulled, not pushed. More amps in a charger just means your phone can draw more without burning out the charger. It does not mean that the charger pumps out more than your phone can handle.
Volts are different. Too much or too liitle volts are harmful but all usb chargers are the same 5v so don't worry about that.
Lastly, unfortunately the different manufacturers have created different special schemes to trigger or allow devices to exceed 0.5 amps (to prevent a high draw device from trying to pull 2.0 amps out of a 0.5 amp usb port and burning out a usb port or possible even all usb ports on your expensive laptop!)
So, merely having a charger that says 2.1A on the side isn't enough by itself. You will still need to try differnt cables and try different models of chargers and even different kernels if you are rooted, or refer to reviews where the reviewer covered this explicitly instead of just saying "It worked great" which is a meaningless waste of everyone's time.
For instance there was another thread about chargers where they found that on a 2 port model that has one port labelled Apple and another labelled Android or just unlabelled, they found that they actually behaved different. The Apple port was 2.1A and the Android port was only 1.0 or 1.5A, yet a GN2 charged faster on the Android port. Because the GN2 didn't recognize the Apple port as being capable of high current, at least not with a standard cable, and so the GN2 was only pulling 500 or 700 ma, while on the Android port it pulled 1.0 or 1.5A.
So you really need reviews and testing that takes all this into account and specifies actual charging times and that make and model of the usb cable used etc. Or just buy the official stuff from Samsung which is all garanteed to match and work as expected without having to know all that unsuspected stuff.

I have quite a bit of cells and tablets, who doesn't, but I also have quite a few rc cars and helis. All the battery's we are using are Li-on although I use a ton of lipo (lithium polymer) on my rcs. Ive built packs, soldered connections, I charge 6 batteries in parallel, etc. I have a 530 watt adjustable 18 Volt 30 Amp PSU connected to a 400 watt 18 volt 20 amp balance charger. Granted if your not in the rc world this would be overkill for sure just to charge your cell battery. Point is you can charge any, repeat any Li-on or lipo battery at 1 C. . 1C is the capacity of the battery. All of my lipo rc battery's can be charged at 5C. That means 5 times the capacity of the battery. In our case the note 2 battery is 3100 mah or 3.1A for short hand notation. So if you have a big enough charger like I do, you can safely charge it at 3.1A in an hour. Some of my bigger packs are 6S 30C 10A packs. That is 22.2 volts 30C discharge rate and 10Amp or 10000 mah capacity and 5C charge rate. If your not familiar with the above jargon no matter, the OEM Samsung charger with the OEM usb cable that comes with it puts out 2.1 or 2100mah per hour or 2.1A . Our stock OEM batteries are 3100 mah or 3.1 A. So they will fully charge in about 1 1/2. Ive timed it several times and that is pretty accurate. This is with the phone being off not on while charging. It will take a little longer with the phone on while charging, about 2 hours. Hope this helps.

You can charge. It is the voltage that must match (and for USB it is standard and equal 5V) And the wattage of the supply(charger) should be greater or equal to the device's wattage.

i don't know about that. i just plugged in a 22,000 watt 5V supply. the phone exploded, blew out two windows of my house and the battery is still lodged in my ass. do you think i need to go to the ER?
If I use the power supply from HTC the touchscreen's response is bad. Drawing gestures on my lock screen doesn't work good. But I'm using if for over a year now, and had no problems. Guess it could be worse for my battery.
Shouldn't be too hard!
You should be able to use the iPad power block with and USB cable... That's my understanding.

I'm not sure of the voltage of the I9305 but the more volts = faster charging but hotter and hotter means a shorter life for the battery but it should be fine, I would trade it for faster charging. For amps, I have no clue and please correct me if I'm wrong anybody.

AW: [Q] Charge with 5V/2A..?
In principle, the battery would load faster at higher charging current when the battery is capable of fast charging. If not, could reduce the battery life. I believe according to the charging control of Samsung, a current limiter is installed that can always draw only 1 amp. So it brings no benefit to using the charger of the tab. It may also be that the charging control of the current is limited so that is not loaded. The phone should not be harmed.

Should be fine for short term use.I've used half amp one amp and one and half amp car chargers wouldn't go any more than two amps no need to..may degrade battery a little so what there cheap enough to replace lol..easy peasy.. I live in tents an caravans 24/7 use leisure battery's not problem with amps just volts..bless solar panels..
The phone take what Amp it needs.. No more than its made for. 2A is only what the maximum out is for the charger.
You could make a charger with 50A, the phone still dont take more.
The volt is the value that need to be fixed though.
All phones charged via a usb needs 5V, no more, no less.(Usb =5V allways) Most batterys now days is something like 3.7V. Correct me if Im wrong.
Any way, you need a couple more volts in the charger than the battery to charge it.
Answere=Yes.. go ahead and charge.

I have had an HTC HD2 and used it's charger to charge my SGSII and now my SGSIII.
The time taken to charge with that is about the same as the SGSIII charger.
The charging circuits on the phone are smart enough to know that you are charging from a mains' adapter instead of an USB output from a computer and thus adapts the current draw from the system.
I previously did tests on the HD2 regardsing charging times and even with bigger supplies that the 1A one from HTC, it did not charge any quicker.

That charging circuit is made to cooperate with the battery and the rest of the phone.
So only difference you will notice is slower charge time if you are using a to weak charger that cant deliver the right amp.
As mentioned earlier you could use a 50A charger with out any faster charging time. Amps is allmoust of no interest if its not to weak.
Look at electricity as water. Amp is like how many liters of water a sertain pipe could deliver. Volts is more like how strong the flow is. To mouch pressure will destroy the flower. But with Amps you could pretend that the flower demands a certain amount of water and it will not suck more just becaus it could get more.

Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.
Sent from my One using xda premium
Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.
I have the VS980 from Verizon.
Does anyone know if there are any portable chargers / external battery packs that will charge this phone without giving an incompatible or "slow charging" notice? If there aren't any that fast charge, are there any that slow charge? Slow charge would still be better than a dead battery.
I find the battery life is mostly great, but some days it seems to run down quite quickly. In any event, I'm going on a trip and may not have access to a charger during day and plan to be taking lots of pictures and videos and listening to music, so I'd like a back-up battery, just in case.
(curse Verizon and their non-removable battery...)
Anyway, there are threads for compatible car chargers, wireless chargers and USB cables, so why not add one for portable chargers / external batteries? Please list them here!

The problem is, it seems that the phone doesn't just go by amperage, but also by the cable. The OEM USB cable has 20AWG wires, which carries a higher load, and cables which have thinner wires seem to trigger the slow charging. The only way to know if these chargers would charge at full speed would be to plug them in.
Has anyone actually plugged any of these in to verify that they do the full speed charging without a 'slow charging' notification?

I would like to disagree but need help understanding why. Maybe I'm wrong and I have a faulty charger.
My charger has two ports. One is 1amp and the other is 2.1amp. My 1amp side seems to actually charge my phone faster than the 2.1amp side. Also with 2.1amp while in listening to music through Bluetooth using GPS and navigation all at the same time, it tells me my phone is dying faster than it's able to charge. With the 1amp side I'm able to hold a steady charge sometimes going up at least 2 percent during a 30 minute drive.

It should be a no brainer that a 2 amp charger will charge your phone faster as opposed to a 1 amp simply because one has more output than the other. But I believe that because of the smaller battery the phones have, they need a smaller amp per second of charge. If not then it may destabilize your battery.
Thats just my two cents though. Dont quote me

HTC put a limit on how fast the phone can charge. The chipset supports rapid charging but at what cost (of the battery)? So to be safe HTC disabled that feature of the chipset. So even if you plugged it into a 4 amp USB connector, you are not going charge any faster than say 1 amp. Don't know what the specifications are on the optimal amperage...

Using a higher amp charger cannot damage the battery. The phone will only pull as many amps from the charger as it needs (probably 1.5 amps max).

Using a higher amp charger cannot damage the battery. The phone will only pull as many amps from the charger as it needs (probably 1.5 amps max).

I am saying motherboard. I don't know about physics, but I know from reading the troubleshooting thread that many people have now expensive bricks because of those chargers

could you possibly link to those threads? I have the dual charger 1&2.1. My results are opposite of op my 1a doesn't charge phone but the 2.1 gains charge while driving even while watching movie! id like to read up if it may be problematic! thx
Htc one battery originally is charged by 5V and 1A charger; Can 5v. and 1.3 A damage the phone?
One thing that nobody here has mentioned is the possibility that your charger might have been wired wrong and the side that charges faster is actually the 2.1mah connection instead of 1mah.
With all of the chargers from everywhere in the world that we get them from and they are supplied from, anything can happen that We don't expect.
Maybe you might want to get it tested with an OHM Meter to verify which connector is the Higher and which is the Lower.

The only thing that is different (as far as the phone is concerned) is whether it sees an AC style charger or DC style. No matter what, the phone will only pull what the charging circuit "says" to pull.

For some chargers, sometimes the 2 Amp port appears to be using the Apple protocol for USB power, so that port will only provide 0.5 Amps to most other devices. And when the1 Amp port somewhat over delivers, and can source 2 Amps if nothing else is connected and 1.5 Amps if the 2 Amp port is sourcing 0.5 Amps for a non-Apple device. Thus some chargers can support one high power non-Apple device (in the 1 Amp port) and one lower power device (in the 2 Amp port). FYI I use this charger bought on Amazon---Avantek. Worked really well, versatile and low profile.

Maybe a myth?
